Hi, I am newly diagnosed Peanut allergy and tree nut allergy. My doc says carry an epi pen at all times. I guess I am severe. I am a little scared of this whole thing. But I am also wondering if I have had this for many years as when I was a kid I would get unexplained hives. Now I don't get hives but get throat and tongue swelling, runny nose. I am 37 now and have 4 kids who are not food allergic. But I am glad that they found this because maybe it caused some of my stomach issues too.
